The control of the voice pattern analysis engine is performed by a microprocessor 286. In charge of If it is determined that the analysis result matches the risk setting reference voice signal, the detected voice signal is synthesized with the square wave in the voice synthesizer 287. Thereafter, the speech signal synthesized with the square wave is combined with the triangular wave to pass a pulse controller 287 for generating square waves having different duty. The pulse controller 287 is preferably formed of PWM (pluse width modulation) for pulse width modulation.

The voice signal determined as a dangerous signal is transmitted to an external receiving station (such as a guard room or a management room) through a power line communication unit (PLC). The power line communication unit converts the incoming signal into a signal of 300 kHz band, and is then transmitted to the receiver 310. The filter unit 320 is provided before the receiver 310 to filter out unnecessary noise. In the filter unit 320, the 60Hz signal, which is a general household frequency signal, may be cut off and set to pass only a 30KHz to 100MHz signal.
